n operation of devices of this character, to ren-v der them economical in manufacture and foolproof in operation.

One of the specific objects of the invention is to provide an improved frictional mounting for the ventilator by which it may be held frictionally in open, closed, or adjusted positions. Y

Other objects and features of novelty will be apparent as the following description proceeds, as taken in connection with the accompanying drawings forminga part of this specification, in which:

Fig. 1 is a vertical section, partly in elevation showing the ventilator as mounted near the top, and under the visor of an automobile, accordingto one ,embodiment of the invention.

Fig. 2 is a horizontal cross section taken along the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary elevational view of the intermediate portion of the ventilator member.

Referring more particularly to the drawings, certain characteristic elements of automobile bodies have been shown in order to clarify the illustration of the novel features of the invention with relation thereto. These elements are the top 10, the visor 11, windshield 12 and body windshield pillar 13, which are constructed with relation t-o each other in the manner customary in the art, with the exception that the windshield 12, while it may be exactly like the usual windshield, is preferably terminated a little short of its usual position, thus leaving room between the windshield and the top for the mounting of the ventilator.

The ventilator comprises essentially aV semicylindrical'member 14 constructed of glass, fiber, metal, or other suitable material and VEN TILATOR 1929. serial No. 374,639.

may .be opaque or transparent as desire-d.. l

nd members 15 are the ventilatorA 14 and otally 16.

provided at each end f provide means for pivsupportlng the ventilator from studs In the preferred form of the invention shown, the member 15 is disc-like with van outwardly directed annular flange 17 which fits inside the lother end of the ventilator 14 and is rigidly secured thereto. Obviously this specific form is not essential as the fundamental purpose of the member 15 is to p'ovide apivotal support for the ventilator Friction means of similar construction are provided vat each end of the ventilator for holding said ventilator 14 in desired positions of adjustment and means associated therewith for automatically taking up Wear and for anti-rattling purposes. The central portion of the member 15 is dished to form a concave, substantially spherical seat 21, in the center of which is provided aperture 22, of

slight-ly larger diameter than the stud 16 which pivotally supports the ventilator. lAn annular bearing member or collar 23 is provided with as herical portion 24 mating with the seat 21. helical spring 25 is interposed between the member 23 and the head'26 of the stud 16 and normally urges the member 23 against its seat.

Referring again to Fig. 1, it will be noted that in the embodiment shown, the upper rail 27 of the windshield is provided with the rubber gasket 28 and that the stud 16 is located to one side of the plane of the windshield and well above the rail 27. The arrangement is such that the lower edge of the ventilator 14 buts against the rubber gasket ventilator on the carv pivot the ventilator and cause the lower edge thereof to swing upwardly away from the gasket 28 and .provide a ventilation opening for the interior of the car.

The member 15 which supports the ventilator will pivot about its seat on the bearing member 23 which is yieldingly held thereagainst by the spring 25. The strength of the spring is such as to hold the ventilator in any desired position of adjustment and also prevent rattling of the moving parts. It will be understood that with a spring 25 at each end of the ventilator, the use of springs of as near equal strength as possible will result inV the centering of the ventilator between the opposite brackets 18y so lthat the end members 15 will be held out of contact with the iiat circular' portions 19 of the said brackets, as best illustrated in Fig. 2, to prevent rattling. The use of the spherical surface 24, on the bearing member 23, with a Y.. similarly. shaped vsurface on the seat 21, `and the provision of an aperture 22 of greater diameter than the diameter of theL stud 16 will enable the mating spherical surfaces to center the end'members 15 with respect to the studs 16 and will take all of the wear 0E of the studs and receive `it on the relatively large spherical surfaces'. It will be noted that the ventilator body 14 is connected at its opposite ends to the side pillars 13 of 'the windshield by means of yieldable connections; namely, the springs 25 bearing against the heads 26 of lthe studs 16 and the bearing members 23. This mounting for. the ventilator permits the latter to be adjusted relative to the brackets 18 kcarried by the pillars 13. This type of mounting for the ventilator body enables the same to, take care of any weaving strains resulting from relative movement of the windshield pillars In the drawings the bracket 18 has been shown in great detail with the studs 16 threaded thereinto as at29 and the bracket is provided with a flange 3() strengthened by a web 31 and secured to the supporting structure by machine screws 32. Obviously the broader idea of the invention is not limited tothe specific details shown and described, but includes such embodiments of the invention as fall within the scope of the subjoined claims.

Having thus described the invention what f we claim as new and desire to secure by Iletters Patent of the United States is:

1. In combination with a windshield ventilator of the type adapted to be pivotally supported between the top of a closed car n supported between the top of a closed car y body and the windshield proper, a pair of brackets secured to stationary parts of the car body carrying pivot members for supporting the yrespective ends of the ventilator, and springpressed friction means for holding said ventilator in various positions of adjustment and centering'it with respect to said pivot members, said brackets being provided with annularflanges adapted to overlie the ends of said ventilator and arranged concentrically and out of contact with the latter,

3. Apparatus of the character described, comprisingin combination, a pair of. opposed brackets carrying pivot members horizontally aligned, a windshield ventilator having its ends respectively loosely mounted on said pivot members, and spring pressed means for retarding the movement of said ventilator about saidpivot and for centering the ventilator axially with respect to the brackets nd radially with respect to the pivot memers.

4. Apparatus comprising in combination, a semi-cylindrical windshield ventilator, a circular member fitted in the ends of said ventilator Vfor 'supporting it about a pivot, a stationary bracket carrying a stud forming the` pivot for said end member,and friction means for retarding the motion of said member about the stud, said friction means including a spherical seat formed on the en-d member and a spring pressed bearing member having a spherical surface mating-with said seat. i

5. A device of the character described, for pivotally supporting a semi-cylindrical windshield ventilator from a stationary support, comprising in combination an end member secured to one endof said ventilator having a central aperture, a bracket supporting a stud of less diameter than and passing through said aperture, said member being dished in the region of said aperture to provide a spherical seat, an apertured bearing member mounted on said stud for axial movement only and having a spherical surface mating with said seat, a helical spring mounted on said stud having one end bearing against the head thereof and the other end bearing against said apertured bearing member for normally urging it against its seat.

6. The combination with a vehicle body including a top, a pair of windshield pillars of the character described,`
